The tascodec_init() of the snd-soc-tas2781-comlib module is called from
snd-soc-tas2781-i2c and snd-hda-scodec-tas2781-i2c modules. It calls
request_firmware_nowait() with parameter THIS_MODULE and a cont/callback
from the latter modules.
The latter modules can be removed while their callbacks are running,
resulting in a general protection failure.
Add module parameter to tascodec_init() so request_firmware_nowait() can
be called with the module of the callback.

A bunch of small fixes that come in during the merge window, mainly
fixing issues from some core refactoring around dummy components that
weren't detected until things reached mainline.
The TAS driver changes are a little larger than normal for a device ID
addition due to some shuffling around of where things are registered and
DT updates but aren't really any more substantial than normal.

ASoC: Fixes for v6.8
A bunch of small fixes that come in during the merge window, mainly
fixing issues from some core refactoring around dummy components that

Move tas2563 from tas2562 driver to tas2781 driver to unbind tas2563 from
tas2562 driver code and bind it to tas2781 driver code, because tas2563
only work in bypass-DSP mode with tas2562 driver. In order to enable DSP
mode for tas2563, it has been moved to tas2781 driver. As to the hardware
part, such as register setting and DSP firmware, all these are stored in
the binary firmware. What tas2781 drivder does is to parse the firmware
and download it to the chip, then power on the chip. So, tas2781 driver
can be resued as tas2563 driver. Only attention will be paid to downloading
corresponding firmware.
